I have a system that I am migrating from a part with more RAM to the STM32H733. I already have external FLASH set up and operating well but the amount of RAM available for heap is anemic for future growth.The external flash is running on the OCTOSPI...

We are migrating a project from H750 to H733 and I have run into an issue with our custom bootloader.We have our own External Loader, Bootloader and Application. Works fine on 750, but I have had to remake the projects for a move to the H733 micro.W...

I'm migrating source that has run for quite a while successfully on H755 to a new project so we can swap to the H733 micro for the increased memory security features.The project is not currently using the external OCTOSPI, building a reduced version ...

We have a project that was working with a demo board with a different micro than our final project uses. We imported into CubeIDE an ioc generated by CubeMX by our hardware engineer. We did a bit of work on the project to include source from a vari...

A Typo, our processor is the H733 so it does support two OCTOSPI and we are indeed planning on using the setup in Figure 12. What I am still not sure on is how much this will impact our access speeds if both external memories are memory mapped and b...

On closer examination it looks like the configuration in Figure 7 page 24 would work for us, mutiplexing between flash and ram.. though their example does not show a PSRAM usage.. The time based multiplexing has to be a hit to speed of course, but w...

Just in case anyone has a similar issue, here was the resolution:The issue was unrelated to the UART driver, it was changes in the SDK and autogeneration between the two projects that caused the ThreadSafe directory to be created. Our project was ha...

Yes, the issue was traced to the the Dummy Cycles configuration for our performance mode. With that fixed, jump works fine.

Thanks for your response Pavel,For the curious, my investigation has moved along and I found that the value on the XSPI for the SP (and everything else) is different when read from the stand alone programmer:Which, as we can see, has the right value ...
